  • Product introduction

AD7440BRMZ   差分输入、1 MSPS、12 位ADC (AD7450A) 和10位ADC (AD7440)

AD7450A/AD7440分别是12位和10位、高速、低功耗、逐次逼近(SAR)型模数converter(ADC),采用全差分模拟输入,工作电压为3 V或5 V单电源,最高呑吐量可达1 MSPS。

这些器件内置一个低噪声、宽带宽、差分采样保持(T/H)放大器,可处理1 MHz以上的输入频率,-3dB带宽典型值为20MHz。 外部基准电压通过VREF引脚输入,可在100 mV至3.5 V范围内变化,具体取决于电源和应用。基准电压值决定器件的共模电压范围。利用这一真差分输入结构和可变基准电压输入,用户可以选择各种输入范围和偏置点。
